You make it sound like any of the conditions are pervasive, they employ 876,000 people, if the conditions were as bad as the media makes it seem I would imagine there being more outcry instead of the media having to blow up specific instances of things happening.

Where there's smoke there is fire is the saying, so maybe it is that bad but that's not what I understand it to be.

Edit: Also from all the documents we've seen it would appear Amazon leaks like a sieve so I would also expect way more damning evidence to have appeared by now.
